• Guidance and manufacturer’s declaration – electromagnetic emissions
The device is intended for use in the electromagnetic environments listed below, and should only be used in
such environments:
Emissions test
Compliance
Electromagnetic environment – guidance
RF emissions
CISPR 11
Group 1
RF energy is used only to maintain device’s operation. Therefore,
its RF emissions are so low that it’s not likely to cause any
interference in nearby electronic equipment.
RF emissions
CISPR 11
Class B
The device is suitable for use in all establishments, including
domestic establishments, and those directly connected to the
public low-voltage power supply network that supplies buildings
used for domestic purposes.
